Reaction Steps

Under an inert atmosphere of nitrogen, 3,4,5-trimethyl-piperazine-1-carboxylic acid benzyl ester (1 eq, 1.87 mmol, 0.49 g) is dissolved in EtOH (20 ml) and palladium on carbon (0.1 eq, 0.187 mmol, 0.2 g) is added. The reaction is stirred at room temperature under an atmosphere of hydrogen for 4 hrs. The reaction mixture is filtered through Celite® and the solvent evaporated under vacuo to afford the title compound.
